Atomic terahertz-vibrations solve the enigma of ultrashort soliton molecules

Stable packets of light waves—called optical solitons—are emitted in ultrashort-pulse lasers as a chain of light flashes. These solitons often combine into pairs with very short temporal separation. Introducing atomic ...

Scientists greatly expand the frequencies generated by a miniature optical ruler

Like a vocal coach who extends the octave range of an opera singer, researchers at the National Institute of Standards and Technology (NIST) have expanded by nearly two-thirds the frequency range over which a chip-scale device ...

New discovery may revolutionize decades-old understanding of integrable hierarchies

Processes in nature can often be described by equations. In many non-trivial cases, it is impossible to find the exact solutions to these equations. However, some equations are much simpler to deal with because of their extreme ...

Creating frequency combs in microresonators

For the first time, scientists were able to create ultrashort dark and bright light pulses that are linked together in tiny glass rings called microresonators. Each of the flashes consist of many different, precisely defined ...

Changing the properties of ferroelectric materials by vacating a single oxygen atom

Researchers in the Technion Department of Materials Science and Engineering have succeeded in changing a material's electrical properties by vacating an oxygen atom from the original structure. Possible applications include ...

A quantum view of 'combs' of light

Unlike the jumble of frequencies produced by the light that surrounds us in daily life, each frequency of light in a specialized light source known as a "soliton" frequency comb oscillates in unison, generating solitary pulses ...

Flattening the curve: Nano-film enhanced supercontinuum edition

Providing light with tailored properties through ultrafast supercontinuum generation represents an active field of nonlinear science research. A German-Australian research collaboration has presented a new concept that includes ...

Separated only by quadrillionths of a second: Ultrashort flashes of light combined precisely and quickly

Ultrashort flashes of light lasting less than a quadrillionth of a second are fast growing in technological importance. In laser sources, pairs and groups of light flashes can be created instead of individual flashes. Similar ...

Topological valley Hall edge solitons in photonics

Diffraction is a natural property of light beams that allows light to bend around obstacles. Because light serves as a carrier of information, some of the distorting effects of diffraction must be mitigated for many technological ...

Ultrafast optical switching can save overwhelmed datacenters

EPFL and Microsoft Research scientists demonstrated ultrafast optical circuit switching using a chip-based soliton comb laser and a completely passive diffraction grating device. This particular architecture could enable ...
